Radiation curable ink-jet printing process using dotsize control fluid |
(57) A radiation curable ink-jet printing process is disclosed, exhibiting consistent
image quality on a wide variety of different ink-receivers. The ink-jet printing process
comprises the steps of:
a) providing an ink-receiver;
b) providing a surface layer on at least a portion of the ink-receiver with a dotsize
control fluid;
c) jetting at least one radiation curable ink-jet ink droplet to the surface layer
on the ink-receiver;
characterized in that the dotsize control fluid contains a surfactant, a film forming
polymeric resin and an inorganic filler, wherein the ratio P/F is greater than 3.0,
with P being the weight% of film forming polymeric resin and F being the weight% of
inorganic filler, both based on the total weight of the dotsize control fluid, and
the surfactant is present in the surface layer in the range of 0.1 to 20 % by weight
based on the total dry weight of the surface layer.
